چکیده :

PM-assisted synchronous reluctance motors (PMa-SynRMs) have recently emerged as a promising option for high-efficiency and cost-effective electric drives. This paper presents a comprehensive multi-objective treatment that includes design, electromagnetic assessment, and thermal analysis of a PMa-SynRM, employing two different magnet materials: neodymium-iron-boron (NdFeB) and ferrite. The developed machine was meticulously modelled using finite element analysis (FEA) to study back electromotive force (B-EMF), torque profile, terminal voltage, and efficiency maps for various loading conditions. Subsequently, thermal 3D simulations in ICEPAK were conducted for several representative operating points to evaluate the temperature distribution in the stator, rotor, winding, and magnets. The findings underscore the thoroughness of the study and the intricate trade-offs between cost, thermal reliability, and electromagnetic performance. These results provide valuable insights for the industrial design of sustainable electric drives, ensuring confidence in the investigation's findings.
